Ktm 125 sx 2003 idles but wont rev up

your pilot circut is clogged. Take out your pilot jet (this is the jet closest to the cylinder) Be sure to spray carburator cleaner thru this jet until the stream is heavy and solid. Next insert the tube from your can of carb cleaner into the hole the jet was in and spray until it comes out in two locations in the carburator. One in the throat of the carb and one directly under the front edge of the slide. Go to the back of the carburator and you'll see a couple of holes at the bottom edge of the carb that mounts to the air box. these are vent holes. Spray cleaner into them and find the hole that vents the pilot circuit and insure it is not clogged. Once all of these are cleaned your bike should run as if new. Good Luck.

I have a ktm sxf 250 2006 model and when its hot it is very hard to kick start even with start assist spray and sometimes will not but it will roll start and also when you are at top of each gear mainly...

Using "Easy Start" or other ether based engine starting aerosols will damage the engines in the long run, reducing compression due to engine wear as the aerosol removes the oil traces off the engine bore and stripping the aluminiun from the pistons. If it were an old diesel engine, not a problem.
Check your petrol mixture settings and compression. As if the compression is low it will be hard to start.

Check your owners manual it will tell you how many cc or oz. to add also on alot of the dirt bikes it is stamped how much to add, buy a measuring cup and add per. bike specs.

If you don't have a manual do a internet search for your make and year of bike for how much oil to add.

There is not a dipstick or a sight glass on most dirt bikes...Hope this helps

Oil change - how much oil do you need to put in the KTM 450 exc when filling with oil??

I use just under a quart however there is on most bikes a number near the filler plug on the case it will have the letters cc next to it this is cubic centimeters of liquid go to the metric to standard conversion chart on the web to find the metric to standard conversion to be absolutely sure of the exact amount for your bike.

Over filled oil yzf 450

Open the air box,clean it from extra oil,renew the air filter if you have to and without the air box-air filter (or opened) try to start the bike while sraying with a carb cleaner spray through the air box towards the carbs.Don't spray too much.Little bit each time and do not twist the gas grip.Choke it too if you want.It may help.Of course before all that set the oil level to normal.
